Abstract
Abstract A coaxial electrical connector for connecting an antenna to a walkie talkie radio or the like includes a center contact member (21) for electrically connecting the antenna (12) to the radio (10), and a collar (23) having bayonet coupling structure (67) for mechanically coupling the connector to the outer contact (71) of a complementary coaxial connector (50) in the radio (10) without electrically connecting the connector to the outer contact (71). Because the antenna does not require coaxial electrical connection to the radio, the outer contact is eliminated from the coaxial connector of the present invention and replaced in support function by a semirigid, dielectric shell (22) which both electrically insulates the center contact member (21) and provides mechanical support to resist stresses caused by loads applied to the antenna. The connector optionally also includes a plastic sleeve (24) surrounding the collar (23) and retained in position therearound, for helping to protect the connector and for providing the connector with a more attractive external appearance.
